Abstract

The invention discloses a power supply control circuit, method and device. The circuit comprises a solar power supply circuit, an AC power supply circuit, a load system and a controller, wherein the solar power supply circuit and the AC power supply circuit are connected to the access DC bus side of the load system after being connected in parallel, and the controller is connected with the solar power supply circuit and used for detecting whether the output power of the solar power supply circuit is smaller than the required power of the load system or not and adjusting the output voltage of the solar power supply circuit when detecting that the output power of the solar power supply circuit is smaller than the required power of the load system so that the load system can be powered by the AC power supply circuit and the solar power supply circuit together. Through the power supply control circuit, method and device, the problem that due to the fact that a compressor of a refrigerator is powered through a photovoltaic power supply assembly and an AC power supply assembly independently, the solar source utilization rate is low is solved.

Description

technical field [0001] The present invention relates to the technical field of circuit applications, in particular to a power supply control circuit, method and device. Background technique [0002] With the promotion of renewable energy, the energy provided by renewable energy alleviates the supply demand of non-renewable energy, and the environmental protection effect achieved by renewable energy has become a must for the current energy trend, so the power supply method of home appliances has also changed. , and how to effectively combine conventional power supply and renewable energy power supply to power home appliances has become an urgent problem to be solved. [0003] In the part disclosed in the related art, a method for controlling the power supply of a refrigerator is provided. When controlling the power supply of the refrigerator, two independent power supply components of the photovoltaic power supply component and the mains power supply component are used to sup...
